Assembly
For Your Safety
Warning! Switch off, remove plug from mains before
adjusting cleaning or if the cable is cut, damaged or en-
tangled.
Caution! Do not touch the rotating chain.
Do not operate the chain saw near other people, chil-
dren or animals. Do not operate the chain saw after
drinking alcohol or under the influence of intoxicating
drugs or medication.
Electrical Safety
Your power tool is double insulated for safety and requires no
earth connection. The operating voltage is 230 V AC, 50 Hz
(for non-EU countries 220 V, 240 V as applicable). Only use
approved extension cables. Contact your Bosch Service Cen-
tre for details.
Only extension cables of design type H07 RN-F or IEC (60245
IEC 66) are permitted for use.
When operating the chain saw with an extension cable, the
following conductor cross-sections are required:
2
– 1.0 mm
: max. length 40 m
2
– 1.5 mm
: max. length 60 m
2
– 2.5 mm
: max. length 100 m
It is recommended for increased electrical safety to use a Re-
sidual Current Device (RCD) with a tripping current of not
more than 30 mA. Always check your RCD every time you use
it.
For products not sold in GB:
WARNING: For your safety, it is required that the plug 16 at-
tached to the machine is connected with the extension cord
15 as shown. The coupling of the extension cord must be pro-
tected against splash water, be made of rubber or coated with
rubber. The extension cord must be used with a cable strain
relief.
The connection lead must be inspected for signs of damage at
regular intervals and may only be used if in perfect condition.
If the supply cord is damaged, it must be replaced by a Bosch
Service Centre.

Mounting and Tensioning the Chain
Saw
Do not connect the chain saw to mains before it is com-
pletely assembled.
Always wear protective gloves when handling the
chain.
Chain and Chain Bar Assembly
(see figures A1 – A3) (AKE 30 S/35 S/1835 S/
40 S/45 S)
– Unpack all parts carefully.
– Place the chain saw on any suitable flat surface.
– Slide the saw chain 9 in the slot around the chain bar 10.
Ensure the saw chain is in the correct running direction by
comparing the saw chain with the rotation symbol 22.
– Fit the chain onto the drive sprocket 20 and guide the
chain bar 10, so that the fastening bolt 21 and the two
guide fins 24 fit into the keyway of the chain bar 10, and
that the chain tensioning peg 25 fits into the respective
hole of the chain bar 10.
If necessary, adjust chain tensioning knob 14 to bring ten-
sioning peg 25 in alignment with the hole in the chain bar
10.
– Check if all parts are seated properly and hold the chain
bar and the chain in this position. (see figure A2)
– Turn the tensioning knob 14 until all the slack is taken up in
the chain.
– Fit cover plate 13.
– Handtighten locking knob 12 on fastening bolt 21.
(see figure A3)
If too tight then the chain can lose tension during use.
The locking knob must only lightly clamp the chain bar.
Tensioning the Saw Chain (see figures A1 – A3
and E) (AKE 30 S/35 S/1835 S/40 S/45 S)
Always check the chain tension before use, after the first cuts
and regularly during use approx. every 10 minutes. Upon ini-
tial operation, new chains can lengthen considerably.
The chain life of the saw chain mainly depends upon sufficient
lubrication and correct tensioning.
Avoid tensioning the chain if it is hot, as this will cause the
chain to become overtensioned and face too tightly against
the chain bar when it cools down.
– Place the chain saw on any suitable flat surface.
– Check if the chain links are correctly located in the slot
around the chain bar 10 and on the drive sprocket 20.
– Loosen locking knob 12 until it is just holding chain bar in
position (do not remove!).
– Turn tensioning knob 14 clockwise until the correct chain
tension is reached. The turning action forces the chain bar
10 forward via the chain tensioning peg 25.
– The saw chain 9 is correctly tensioned when it can be
raised approx. 5–10 mm from the chain bar in the centre.
